Improvement in car-axle boxes



UNITED STATES PATENT OFFICE.

HIRAM G. FEGER, OF POTTSTOWN, PENNSYLVANIA, ASSIGNOR OF ONE- FOU RTH HISRIGHT TO JOHN H. HOBART, JR, OF SAME PLACE.

IMPROVEMENT IN Specification forming part of Letters Patent No. 188,118, dated March 6, 1877; application filed February 16, 1877.

To all whom it mwy concern Be it known that I, HIRAM O. FEGER, ofPottstown, Montgomery county, Pennsylvania, have invented a new anduseful Improvement in Axle-Boxes, of which the following is aspecification The object of my invention is to so construct an axle-boxthat the oiled waste, or other lubricating material, will always beretained in its proper position in the bottom of the boxan object whichI attain in the man ner hereinafter set forth, reference being had tothe accompanying drawing, in which- Figure 1 is a sectional plan view ofmy improved axle-box, and Fig. 2 a vertical section of the'same.

A is the casing of the box, and B the cover of the same, the latterbeing ribbed at the lower end, and adapted to the edge of the opening inthe front of the box, and being retained in position by a plate or key,a, which passes through a slot in the projecting top I) of the box, andthrough a slotted lug, d, on the cover-plate.

D' is the axle, having the usual flanged end 6, journal E, and shoulderf, the journal bearing against a block, 13, in the top of the box,between which and said block intervenes a recessed fil1ing-piece,g.

to the shouldered'portion f of the axle, are

arranged projecting plates 11, similar plates j projecting from thecover-plate B of the box, and embracing the flange e. By means of theseplates'i and j 1 am enabled to overcome serious objection to ordinaryaxleboxes-- namely, the tendency of the flange e and shoulder f, whenrevolving, to carry up portions of the lubricating material from thebottom of the box, these portions becoming lodged in the top of the box,and, when dry, generating such a degree of friction as to becomeignited, or to otherwise seriously interfere with the proper operationof the box.

Oil is introduced into the interior of the box through an opening, m, inthe coverplate B, this opening being in line with the plate a, whichthus serves not only to keep the cover B in position, but to prevent theentrance of dust into the interior of the box through the opening m. Theplate a can, however, be raised sufficiently to permit the introductionof the spout of an oil-can into the opening m without disturbing thefastenings of the cover B.

Entrance of dust into the box at the inner end is prevented by aspring-plate, J, which is adapted to guides in the interior of the box,and embraces the lower half of the axle.

It will be evident, that although I have shown the plates '6 on thesides of the box, and the plates j on the cover-plate, both sets ofplates may be formed on the sides of the box, if desired. I prefer toarrange the plates j on the cover-plate B, however, for this reason,that upon removing said cover-plate the interior of the outer end of thebox is left entirely unobstructed, so that old lubricating material maybe removed, and a new supply introduced, without difficulty.

I claim as my invention-- 1. The combination of a car-axle with anaxle-box having plates for preventing the axle from carrying thelubricating material into the upper portion of the box, as set forth.

2. The combination of the axle D, having a flange, e, and shoulder f,with platest' i and jj, as set forth.

3. The combination of the axle D with plates 2' t" on the sides of thebox and platesj j on the cover-plate B, as specified.

4. The combination of the axle-box A and its slotted projection b, thecover-plate B hung to the box, and having a slotted lug, d, and openingm, and the retaining key or plate a, as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

HIRAM G. FEGER.
